February was National Tooth Decay Awareness Month, and it was dedicated to highlight the increase in tooth decay in the youth living in the U.S. In fact, the age gap from 5 to 9 years old is the gap increasing in tooth decay incidents. In an effort to prevent decay and provide healthier smiles, many municipalities are adding fluoride to their drinking water supplies. Some have been adding it for many years.
Water fluoridation is seen more in bigger cities, and has shown improvements in tooth health. However, scientists argue that this method may have some drawbacks, specifically when it comes to mental health.
Studies conducted in England, another country to practice water fluoridation, determined that that rates of underactive thyroid were higher (30 percent more likely) in areas of greatest fluoridation. This means that areas with higher than .7 milligrams per liter of fluoridation in municipal water at risk. In the US the amount of fluoride in drinking water is .7 to 1.2 milligrams per liter.
An underactive thyroid can cause mental and physical health issues such as depression, weight gain, fatigue and aching muscles.
What do you think, should we still keep adding fluoride to our drinking water?
